A 0.2 kg object is attached to a horizontal spring undergoes SHM with the total energy of 0.4 J. The kinetic energy as a function of position presented by the graph.
Just ask: "Help me solve this problem."
A pendulum bob of mass m on a cord of length L is pulled sideways until the cord makes an angle θ with the vertical. The change in potential energy of the bob during the displacement is:
Two balls are thrown off a building with the same speed, one straight up and one at a 45° angle. Which statement is true if air resistance can be ignored?
A force F is exerted by a broom handle on the head of a broom, which has a mass m. The handle is at an angle θ to the horizontal. The work done by the force on the head of the broom as it moves a distance d across a horizontal floor is:
A 90 kg individual is cycling up a hill inclined at 30 degrees on a 12 kg bicycle. The hill is quite steep, and the coefficient of static friction is 0.85. The cyclist ascends 12 meters up the hill and then pauses at the summit. If they then start descending from the peak at rest and travel 9 meters before firmly applying the brakes, causing the wheels to lock.
A 0.50-kg mass is attached to a spring constant 20 N/m along a horizontal, frictionless surface. The object oscillates in simple harmonic motion and has a speed of 1.5 m/s at the equilibrium position. What is the total energy of the system?
A pendulum bob of mass m on a cord of length L is pulled sideways until the cord makes an angle θ with the vertical. The change in potential energy of the bob during the displacement is:
